Ramsey defeated Grace Na, 19, of Anaheim, Calif., 3 and 1. Ramsey, a rising high school senior, was 3 up after 12 holes. Na rallied briefly with a birdie on the 14th. Ramsey was dormie-2 at the 17th when she made her fourth birdie of the day to win the match.

“Ashland outplayed me today,” Na said. “I was even par, but it is what it is. She was consistent. She hit a lot of fairways and greens.”

At the scoreboard, Ramsey, unaware of Na’s comment, concurred. “I try to hit a lot of fairways and greens,” she said. “I’m trying to play it match by match.”

With thunderstorms developing to the southeast and west of the golf course, USGA officials are watching the skies as the afternoon’s semifinals get underway.

“We hope to get the matches in,” said Teresa Belmont, USGA director, U.S. Women’s Amateur Public Links Championship. “There’s the potential of thunderstorms before 5 p.m., so we’re going to keep an eye on it.”
